Heniochus diphreutes

Take a look at the anal fin and where the black stripes meet ... they are different.
Turns out that my 3 beauties are Heniochus diphreutes
I was real worried cause I really did not relish the idea of trying to catch them ... lucky my 12 yr old daughter thought it would be cool to take a pic of them and I used that to compare to the 2 types above.
Good luck on your tank too
Cheers
